END PROTECTOR FOR ROLLS F SHEET MATERIAL.

Application filed November 27, 1922.

1 shocks incident to shipment, and in general to improve prior devices of this character.

For the purpose of illustrat ng the invention, one concrete embodiment thereofis shown in the accompanying. drawing in which Fig. lis a perspective View of one end of a roll of sheet material showing the 'improved protector in use;

' Fig. 2 is a vertical sect on viewof the parts disclosed in Fig. 1;

Fig. 3 is a perspective view of the I tector when in use; and

Fig. 4 is a plan view of the to bending the tabs.

The embodiment of the invention chosen for the purpose of illustrat on comprises an end protector of the general shape when in use disclosed in Fig. 3 and comprises a cap or plate 5 of sheet material in the form of a disk of a size and-shape to fit the end of a roll of sheet material A, such as carpeting or oil-cloth or the like to be protected, and having tabs 6 extending from the periphery thereof. When the protector is ap phed to the end of a roll the tabs are bent to extend about the sides of the roll and serve not only to keep the cap centered upon the end of the roll, but also to hold the cap in place with suitable fastening means which may comprise a band B of rope or wire encircling the roll and securely holding the tabs 6 thereagainst. The preferred rrangement of protectors upon the end of 8. r ll of I material is disclosed in Figs. 1 2 in which a plurality of protecting caps 5, in th s case two in number, are applied in superposition to the endtof the roll, the tabs 6 thereon being disposed in alternation about the periphery of the roll. While but two proprotector prior tabs 6 have been disclosed on each of the.

caps 5, it is to be understood that any de- Serial No. 603,414.

sired number of such tabs may be provided. In order to give a maximum amount of protection, the end protectors are preferably constructed of sheet material which is cellular or otherwise compressible in structure and is thus able to absorb shocks; see Figs; 3 and 4. A material of this character particularly suitable for the purpose by reason of its cheapness is corrugated paper. The preferred method of making the end protectors is to blank them from sheets of corrugated paper. The form of the blanked protector in plan is shown in Fig. twith the extensions or tabs 6 integral with the disk or cap 5. In applyng the end protectors, the disk or cap 5 is placed in engagement with the end of the roll A and the tabs 6 are bent over the end of the roll and into engagement with the periphery thereof in an obvious manner. The usual wrappings about the roll may then be utilized to hold the protectors 1n place, or they may be secured on by bands B as shown.

It will be apparent from the above that end protectors according to this invention are inexpensive to produce and easy to apply.

en constructed of compressible or cellular material they will absorb the shocks incident to shipment to a high degree, particularly when a plurality of protectors is applied in superposition in the manner disc osed in Figs. 1 and 2.

The corrugated paper stock from which the protectors are made may consist of flat top and bottom sheets with the corrugated sheet between as disclosed in Fig. 3, or of a single fiat sheet with the corrugated sheet thereon as shown in Fig. 4. The corrugations may be. disposed transversely of the tabs rather than longitudinally as shown, but! such an arrangement has the disadvantage that the tabs tear away from the cap more easily.

I claim:

1. In combination with a roll of sheet material, means for protecting the end thereof comprising a plurality of superposed disks of cellular sheet material engaging the end pf the roll, tabs on each of said disks bent at an angle thereto to engage the periphery of said roll, the tabs on the respective disks being alternately disposed relative to each said .discs disposed axially of the "roll, the other, and means encircling said roll and 'setabs on respective discs being, alternately discuring said tabs thereagainst. posed relative to each other, and means for 2. In combination with a roll, means for securing the tabs to the roll. protecting the end thereof comprising a plu- Signed by me at Natick, Massachusetts,

rality of superposed compressible discs enthis 22nd day of November, 1922; gaging the end of the roll, tabs on the end of AGNES LEVEN.
